Title: Zero point correcting method in highly accurate differential pressure measuring apparatus
Inventor: HOSOMA TAKASHI
IPC: G01L13/00
Filed: 1991-09-04
Abstract: PURPOSE:To obtain a zero point correcting method which is effective to correct not only the movement of a zero point resulting from the temperature change, but the movement of the zero point due to the pressure applied in common to both ends of a differential pressure transducer of a highly accurate differential pressure measuring apparatus. CONSTITUTION:When a zero point is to be corrected from the measuring state of a differential pressure transducer 6 while a valve V1 of a high pressure piping 5 and a valve V3 of a low pressure piping 7 are opened, with a valve V2 of a shortcircuiting piping 8 being closed, the valve V1 of the high pressure piping 5 is closed as the valve V3 of the low pressure piping 7 is remained opened, and then the valve V2 of the shortcircuiting piping 8 is opened. As a result, the residual pressure at the high pressure side of the differential pressure transducer 6 is freed to the low pressure side. When no pressure is left between both ends of the differential pressure transducer, the valve V3 of the low pressure piping is closed to correct a zero point.

Title: Preparation of sample for trace analysis
Inventor: SANNOMIYA MITSUO
IPC: G01N21/35
Filed: 1983-11-30
Abstract: PURPOSE:To facilitate the formation of a very small tablet sample with excellent transparency by filling a tiny hole bored in a metal plate beforehand with a sample to be molded to perform a compression molding through a soft metal arranged at one end of the tiny hole. CONSTITUTION:A tiny hole in an aluminum plate 1 placed on a press base 10 is filled with a sample powder 3 to the full capacity and then, a soft metal (e.g. indium) 5 is put abutting thereon. Subsequently, the sample 3 is sandwitched between hard metal jigs (not illustrated) such as iron allowed to force the soft metal 5 into the tiny hole by a pressure to perform a compression molding. In this manner, a higher and more uniform pressure can be applied on the sample powder filled in the tiny hole even when the pressure applying to the compression molding is such a low level as about 10-20kg/cm<2> and hence, a tablet- shaped sample can be obtained with a higher transparency.
